    • There is provided a semiconductor package configured for externally controlled power management. Instead of integrating voltage regulation on-chip as done conventionally, power regulation is moved externally to the PCB level, providing numerous package advantages including size, simplicity, power efficiency, integration flexibility, and thermal dissipation. In particular, the use of flip-chip package configurations provides ready access to power supply bumps, which also allows the use of a universal receiving PCB and power supply through simple reconfiguring of voltage traces. As a result, flexible power management can be implemented, and portions of semiconductor packages may be managed for performance or thermal considerations, which may be of particular use for applications such as multi-core processors.
    • 提供了一种配置用于外部控制电源管理的半导体封装。 功率调节不是像以往那样集成电压调节片上,而是将功率调节从外部移到PCB级,提供了许多封装优势,包括尺寸,简单性,功率效率,集成灵活性和散热。 特别地,使用倒装芯片封装配置可以方便地访问电源突点,这也允许通过简单重新配置电压迹线来使用通用接收PCB和电源。 因此,可以实现灵活的功率管理,并且可以管理半导体封装的部分以用于性能或热考虑,这可能对于诸如多核处理器的应用特别有用。
